Has anybody seen light bleed like this?

Looks as if I'm going to have to join the return game on this device. I've been a very happy TF700 owner on CROMi-X for the last year and still had that WOW effect when I started playing with this tablet.
Until it got dark.... I mean - the attached picture is with the tablet in sleep mode!!!!! That's gotta suck the battery dry like nothing.....
Opened a ticket with Asus for what it's worth...
I'm going to update to 4.3 manually, but don't expect that'll do much.
Does anybody have something similar?

Edit: After about an hour of reading the screen dimmed and had dark shadows on both sides. I flashed the 4.3 update manually since the System Update wouldn't - now everything seems to be fine.
Light bleed gone when in sleep mode and no shadows either... ?????????
